Version 3.1 August 2025

This version 3.1 release brings an exciting integration with Vetsource for online prescriptions, as well as enhancing features within Health Care Plans and the Diary.


Vetsource integration

We’re excited to announce a NEW Merlin integration with our trusted partner, Vetsource! This integration introduces seamless workflows to help veterinary practices efficiently manage prescriptions and recommend products directly to their clients.

Two New Workflows built within Merlin:

Vet Recommendations:

Practices can create recommendations for pharmacy or food products available for pet parents to purchase on their dedicated Vetsource website. These recommendations can be:

  • Pre-approved (eliminating the need for approval before fulfilment).
  • Simple recommendations for client consideration.

 Vetsource-Specific Approval List:

A dedicated approval list allows vets to approve or deny prescriptions after a pet parent makes a purchase on the practice website.

With both workflows, the patient record is automatically updated in the history to reflect the actions taken by the Merlin user.

HCP Colour – hover over behaviour

Currently, when "HCP Colour" is enabled, and you hover over a Patient in the reception screen, the colour of that row goes grey, making it difficult to know which plan/tier that patient is on. We have changed this so that the colour will no longer change, instead when hovering over the patient the cursor will change from an arrow pointer to a hand pointer (to be consistent with behaviour elsewhere in Merlin).

Diary Default Day enhancement

We have enhanced the Diary Default Day behaviour so that if “Last Selected Date” is enabled this will now also work with days in the past rather then returning to the current date.

We have also:

  • Removed the SmartFlow settings screen: As this is managed internally by MWI. 
  • Updated the Client Notes tab: The Operator field has been renamed as initials for consistency with the rest of the system.
  • Refreshed the About Merlin popup: The About Merlin popup has been refreshed, the version number of merlin has also been removed from the login screen and bottom corner. It can still be found in About Merlin.
  • Improved the document preview and edit window: We have changed how document information is displayed to reduce the size of the window header and give more space to the actual document
  • Improved alignment of text: We have improved alignment in some areas of the application i.e. Balance/Draft labels and Client and Patient information.
